SURGICAL INSTRUMENT.

Specification of Letters Patent. Patented Nov, 22, 1921,

Application filed April 13, 1920. Serial No. 373,520.

To all whom it may concern.

Be it known that I, AAREIEL E. GoonLon, a citizen of the United Statesof America, residing at Chattanooga, in the county of Hamilton and Stateof Tennessee, have in- Vented certain new and useful Improvements inSurgical Instruments, of which the following is a specification.

This invention relates to certain new and useful improvements insurgical instruments of that class designed. for insertion into thenatural passages, organs and cavities of the human or animal body forinspection and for the removal of foreign matter and bodies and for thetreatment of the body or other similar surgical operations.

The chief improvement consists in combining a tube orbarrel for theordinary uses for which instruments of this class are used, with a jawor blade at the outer extremity of the tubeso constructed that the jawand tube combine to grasp certain objects and at the same time vision ofthe object is maintained. The same principle is involved when, by addingcertain and special knives at the outer or tip end of the tube, certainsurgical operations may be performed, and tissue can be held so as to beinspected, diseased tissue and tumors or other growths can be removedfor examination and other purposes.

While the improvements forming the subject matter of my invention may beapplied to any tube of suitable size and shape for the insertion of thesame into passages, etc, of the human body, and for the removal ofbodies, etc., from any cavity, opening or passage of the human or animalbody for the purposes stated, the invention will be described inconnection with a bronchoscope, designed to facilitate inspection andparticularly the removal of foreign bodies from the human bronchi, asthe instrument is illustrated in the accompanying drawing, in which-Figure 1 is a side elevational View of a bronchoscope consructed inaccordance with the present invention and with its parts in their normalposition, the handle being partly broken away,

Fig. 5 is a plan view of the jaw carrying Fig. 1, parts being brokenaway and parts strip,

Fig. 6 is an elevational View of the outer end portion of the deviceshown in Fig. 1 with the jaw raisedor in the first step of its movement,

Fig. 7 is a view similar to Fig. 6 with the jaw and associated membersin the second step of their movement.

Fig. 8is a view similar to Fig. 7 with the jaw in its third step ofmovement or first position in closing, and

Fig. 9 IS a longitudinal sectional view of the outer end portion of thebronchoscope with a modified form of carrying member 7 for the jaw.

The four positions of the jaw disclosed in Figs. 1, 6, 7 and 8 arerepresented for convenience of description by showing the four stages ofopening and closing of the jaw.

Like reference characters indicate corresponding parts throughout theseveral views.

Referring more in detail to the several views, the present inventionincludes a long tube or barrel 5 which is open at both ends and has asuitable handle 6 rigidly fastened on one end thereof so that clearvision may be had through the tube at all times. A sheet metal strip 7of the. form more clearly shown in Fig. 5 is slidably disposed upon theupper portion of the barrel 5, and this strip 7 is arch-shaped in crosssection as clearly shown in Fig. 4, while the forward end of said stripis forked and apertured to provide a pair of cars 8 to which the jaw 9is hinged adjacent the inclined forward end of the barrel 5. The rearend of the'strip 7 is slid-ably extended through aslot in the handle 6,and at set screw 10 is threaded into the handle 6 so that its inner endbears upon the upper face of the adajcent portion of the strip 7. Theoffice of the screw 10 is to adjustably resist movement of the strip 7longitudinally relative to the barrel 5 as will presently becomeapparent, and said and this'rod 13 is pivotally connected at strip 7 isprovided with a head 11 upon its inner end so as to prevent the stripfrom moving forwardly through and out of the slot in the handle 6. Thebarrel 5 is, provided with a suitable shield 12 within which the forwardportion'of the strip'7 slides so that contact of the strip 7 with thewalls of I the passage ofthe human body isiprevented.

I A rod 13 is slidably disposed Within a--lon---- latitudinal rem vlermv n "the, pp

portion of the barrel 5 beneath the strip 7,

its forwardend to the ,jaw 9 as atg15 and "has its inner endbentupwardly so as to freely extend through the longitudinal elo-ngatedslt'16 provided in theljaw carrying; I strip 7, and to extend through aperforation in theQfinger piece or slide 17 which is n 19untedfjupon thebarrel 5" adjacent the handle 6 whereby, when said slide orfinger pieceis moved longitudinally of the barrel 1 '5 similar movement is'impartedto the rod 1 13.

When fthe finger piece 17 is moved forwardly, the controlling rod 13 iscaused to nove forward so as to .swing'the jaw 9 jaw is accomplished bythe same "principle or: general operation but the order ofmove .mentlsl'eYBISBCl. In other words, for;closmg the aw, the finger piece 17 is(inwardly or rearwardly, upon the barrel 5 40; rear inner. end of therod 13 engages the inner end wall of the slot 16 of the strip 7 so as tocause a pull upon the controlling rod-13 and lower the jaw to theposition of Fig. SwWVhen this takes place, the angular and causes theLlatter, to slide rearwardly until the jaw is returned to its normalposition as shown in Fig. 1. The controllingrod-l3palwaysmovestforwardly or backwardly 'before the sliding piece or strip 7moves, due to the friction on said controlling en 5 o a,

ro'di18being less than that on the sliding a piece or strip 7This-greater friction. upon the strip 18 illustrated as obtainedby meansof the screw but other means may b utilized, on such friction may beobtained by. placing the thumb oringer on strip 7.

The finger piece 17,includes a tubular body having fingerreceivingrings'18, rigidly connected thereto and extending upwardly and downwardlytherefrom; The'body of the fin -er oiece 17 is orovided with an eni D vn w 1 I largem'ent 19 on 1ts underslue through w hlch extends a radialslot 20, having a locking slide 21 disposed to slide upwardly. anddownwardly therein for engagingtherough- 1 ened upper surface 22 withthe under surfaceof 'strip'23, or for disengaging said face The light isilluminating the interior oftube and pasmoved from the strip 23 asdesired, the strip 23 being soldered or otherwise fastened at theunderside of the barrel .5 within the finger piece 17 to the tube 24'.The tube 24: is rigidly fastened to the under side of the l barreh an dopensatits distal end into the tube 5, alongside and adjacent to theapervture- 32 of the drainage tube 31. The relative position of thelight and the distal opening of drainage tube is shown in Fig. 2 at '32and 25, the perforation 32 being' adjacent light 25 fore/securingperfect drainage of region adjacent or near the light. Thus as will beseen, the upper and'lateral vsurface'of-lightglobe is adjacent to theopening of drainage'tube and the lighttrays emanatefromthe bottom of thedistal end of tube 5. V V utilized for the i purpose of sage in whichthe-instrumentisused, and

the wires from the'lamp 25 which are broadly shown in Fig." 1 at 26,--'are extendedlrearwar'dly through the tube 2 L to a- 1 suitable sourceof electricity'. This source of-electricity may reside intheordinaryform of dry cell battery which may beca'rried in-the ocketofthe operator-and flexibly connected to the bronchoscope. a

'The locking slide 21'is of suchlength as to extend-below theenlargement 19 of the finger piece 17 and is provided in its lower endwith; atraji'isverse inclined elongated slot 27 into which extends thelaterally extending pin 28 -w-hich' is rigidly carried by a fingeroperated lever 29, the lever 29 being pivoted as at 30-to the fingerpiece 17 so as to be swung forwardly or rearwardly as des red As theslot 27 1S inclineddownwardly, and .rearwa'rdlyit will be. seen thatwhen the lever 29 is'pressed rearwardly, the

slide 21 is caused to rise until its face 22 en-' gages the strip 23,andthe finger piece 17 is thereby effectively held against movementonand r'elative to the barrel 5. sothat the jaw 9 is effectively heldand maintained in anyof its positions I whenafound. necessary. By thismeans, the operator is on abled to obtain a strong grasp on any objectwhich n'iay be within the grasp of thejaw 9.

His somewhat usualin the present class of devices to place adrainageltube atthe top of the barrel 5, andthis is quite impracticalwith thepresent construction and somewhat undesirable; I place; :thisdrainage tube alongside of the tube: 24; as shown at 31 and thereby makeuse of the space formed vby the joining of the tube 24 to the barrel 5.The drainagektubecommunicates at its forward end with 5116 111061101oftlie barrel 5-by means of a-penforat1on 32 provided in the latter atits forward end, and adjacent to the upper surface of'the light bulb 25,both drainage tube Bland light carrying tube 24 l opening Jadj acent andwithin 1 the forward end of barrel 5, The drainage tube end of thebarrel 5 and has a set screw 35 threaded therethrough so as to engagethe barrel 5 and offer frictional resistance to the sliding movement ofthe sleeve 34. It is to be understood that the construction of thebronchoscope will be substantially iden tical in Fig. 9 as in the otherfigures with the exception that the strip 7 is eliminated and the sleeve34: is substituted in its place.

It will be understood that the jaw 9- may be given simple opening andclosing swinging movements from the position of Fig. 1

to the position of Fig. 6 and then back to the position of Fig. l bythreading the set screw 10 into firm engagement with the strip 7 or theset screw 35 with the barrel 5 when found desirable.

From the foregoing description it is believed that the construction andoperation as well as the advantages of the present invention will bereadily understood and appreciated by those skilled in the art.

It is of course to be understood that minor" changes may be made in theform, combination and arrangement of the various parts hereinspecifically set forth without departing from the spirit and scope ofthe invention as claimed.
